Could be a power problem... I had something like that happen when I added a new card. All but one card crashed. I just used and old 500w power supply to run that card that I added and problem is solved.. Hope this helps... ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

Seems, that it is working! Thank you so much!
I decreased power in AB to 50% and it is working.
I am on remote access on that PC, asked to check power supply's.
Glad I could help.... May want to use an old Power supply to power one or two cards so you can run full bore...lol Take care....
